Sometimes it's necessary to run some tests or debug specific issues in Blesta. Here are some common things you may need to do, or may be instructed to do by support, when something goes wrong.
Check PHP CURL, outbound TLS Version
Blesta integrates with many 3rd party services and it may be necessary to ensure that your server is capable of making a TLS connection with certain minimum requirement. Here's sample code you can place on your server and access in your browser. It will return the most modern version of TLS that your server is capable of negotiating. If it say TLS 1.1 and the service you are connecting to requires TLS 1.2, then it will explain why a connection is not possible.
<?php
$ch = curl_init('https://www.howsmyssl.com/a/check');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
$json = json_decode($data);
echo "<pre>TLS version: " . $json->tls_version . "</pre>\n";
?>
Copy the code into a text file named curl-check.php and upload to your Blesta installation directory. Access in your browser and it will display the most modern TLS version supported. e.g. TLS version: TLS 1.2
